Events of Bright Falls (mini-series)
When Jake Fischer visits the Oh Deer Diner in Episode 4, he spots a Shel Dyke throwing rocks at a lamp post and Deputy Mulligan's attempt to halt the vandalism. Mulligan stops his patrol car near the old lady and gets out of the car. Mulligan demands that she stop, but instead get a rock hurled at him. He places the strange woman under arrest and puts her in the back of his car, but not before she bites him in the hand. He goes into the Diner, shows his bleeding hand to Rose and asking for some first aid. In Clearcut, After Sam Smith's mysterious disappearance, Mulligan goes to the Mountain Air Hotel to ask if anyone there had seen Smith. Because Jake is the only current guest there, he visits his room. Jake lets him in and Mulligan sees that the interior of the room has been completely destroyed. Jake, thanks to his camera, is pretty sure he himself destroyed his own room but doesn't tell Mulligan this. Instead he comes up with the excuse that he left the door open and a wild animal wandered by. Much to Jake surprise, Mulligan observes that the evidence points towards a big deer stag and shows him several telltale signs to back up his point. The deputy then lightly remarks that it would have been a very good hunting trophy and he can't wait to tell his friends about it. It seems that Mulligan did not suspect Jake as the cause of the damage.
